Jessica Alba is proud of her butt

Jessica Alba prefers butts to breasts.

The 34-year-old actress has confessed she is more concerned with having a derrière that is admired by her husband Cash Warren than a chest he notices because the "booty" never goes out of fashion, and all men are obsessed with that feature on a woman.

Speaking to Glamour magazine about her most-desirable body part, Alba - famous for having a particularly perky butt - said: "Boobs come and go, but butts are always in. The butt's always been celebrated. I don't know one man that isn't into booty. And I feel like women, more often than not, women like their butts and it's more accepted (to have a big butt)."

The 'Sin City' star has partnered with DL1961 brand, which specialises in denim - with the DL relating to the denim/leather mix of the material- to help women who may not be as genetically gifted as her achieve their perfect behind.

The Honest Company co-founder - who has two daughters, Honor, seven, and Haven, four, with Warren - said: "I wanted to have high-waisted jeans that look really good on all different kinds of bodies. I wanted it to be kind of tighter in the thigh, but I didn't want the booty to be pressed down. I also wanted it to be nipped in at the waist, and the pockets in the back to be tilted in a V shape, to give you that great round, curved butt.

"If you don't necessarily have a booty, these jeans will make you look like you have a bigger one, which is nice. These jeans will give you that perfect apple - or peach."

The 10-piece fall 2016 line, which features ripped-knee jeans, flared and cropped styles in a variety of dyes and denims strengths, goes on sale in August.
